SPIRAL LEG-BAN D.

Application filed July 28,

To all whom it may concern:

Be it known that I, MAX BAYERDORFFER, a citizen of Germany, residing at Huguenot Park, in the county of Richmond and State of New York, have invented certain new and useful Improvements in Spiral Leg-Bands, of which the following is a specification.

The invention relates to leg bands such as are used in identifying or grading of fowl and the main object is to provide a device which is light in construction and which can not be detached by the fowl picking at the same.

Another object is to provide a leg band having a name plate attached and which also looks the ring on the leg of the fowl.

These and other objects will become apparent in the description to follow in which like-named characters in the specification refer to like-named parts in the drawings, and in which:

Figure 1 illustrates the application of the device on the leg of the fowl.

F ig. 2 is an enlarged perspective of the leg band showing the overlapping ends.

Fig. 3 is a side View of the leg band with the name plate in place.

Fig. 41 is a side view of band and ring assembled.

Fig. 5 is an enlarged fragmentary cross sectional view showing the leg band locking means, the section being taken on line 5-5 of Fig.

Referring more in detail to the drawing, the numeral 10 represents a fowl having a leg band 12 on one of its'legs. The leg band is circular in cross section and is helically wound so that the ends 13 will overlap for about half the circumference of the-leg band and will have a sharp taper 14 located in such a way that the entering wedge of the leg band will be adjacent to the other end of the band.

The name plate 15 is curved so as to conform to the curvature of. the leg band and can Specification of Letters Patent.

be of some light sheet metal suitable for having some inscription engraved thereon. lhe name plate has four extending lugs so curved that they will slidably fit over the two ends of the overlapping part of the leg band. When the device is fitted on the leg of a fowl the name plate is moved to a position directly opposite to the overlapping ends thereof, and the ends are then spread apart so as to allow the leg of the fowl to pass through the coil into the space 17 The name plate is then slid around the leg band so that the cars 16 and 16, 16 and 19 encircle the overlapping ends. The leg band is locked in this position by car 18 adapted to engage the flat surface of the taper 14, drawing the overlapping ends of the leg band into closer contact, the ear 18 being retained upon the wedging surface 14 by means of the ear 19.

Thus it is apparent that there has been provided a spiral leg band which accomplishes the object above mentioned.

I claim:

l. A leg band comprising a slightly flexible coil the ends of which are adapted to overlap each other, tapered surfaces on the ends thereof, a name plate having extending'lugs adapted to encircle the overlapped ends of said coil to slidably retain said name plate thereon, and means for locking said overlapping ends.

2. A leg band comprising a flexible helical coil the ends of which are disposed substantially opposite each other and adapted to spirally overlap tapered surfaces on the ends thereof, a name plate having extending lugs adapted to encircle the overlapped ends of the coil and slidably retain the plate thereon, an additional lug adapted to engage one of the tapered surfaces of said leg band and retain the overlapped ends in contact with each other, and means for locking the coil in position.

In witness whereof I aflix my signature. MAX BAYERDORFFER.
